摘要： A battery-powered accessory monitors an output voltage reduction of the battery as well as the amount of transmitting/receiving data at all times. When a voltage drop of the battery is detected, the accessory displays communication information including the amount of data which have been sent or received by that time. The data transmission brings to a halt at the time when the battery voltage drop is detected. Since a user can easily obtain the communication information through the display, it is immediately determined whether all the data have been transmitted. Furthermore, the user can easily discriminate the data including possible errors due to the battery voltage drop from all the data received. After a battery is restored to a sufficient voltage, the data transmission is resumed automatically. The data may be retransmitted from the following data.
